The original post asked for "all the relations between them." I would be amazed if even IBM has such a map. The now out-of-print logic manuals contain useful maps of certain control blocks with many relations between them, but only for the components whose logic IBM chose to document in their logic books. E.g., the IOS internals logic (two volumes) of the 17-volume MVS/XA logic library, published in the early 1980s, contains excellent maps of most of the low-level control blocks that are involved with scheduling and processing of I/O requests. There is a massive colored diagram of DB2 control blocks and their interrelationships that is about four feet squared, but that is only DB2. If you were to draw a map of all 1,000 control blocks and all their interrelationships, it would be so big and look like such a convoluted nest of snakes that it would probably be unusable. There are also control blocks that exist only in the hardware, and not all of them are documented in generally available publications like the Principles of Operation. We need more specificity from the original requestor. >What I think petitioner wants/needs is a >guide to MVS control blocks, which becomes a guide to MVS internals.
